my english is not so good so let me describe it again for missunderstandings. I never said that you will see it at the next fiat or ferrari model. I fix this from every old parts that i have spare at my garage. I fix that for my punto for track day use. The deferent from selespeed is that i can adjust everything like i want. The selespeed needs calibration because uses one multyposition actuator this one uses as you see deferent cylinder and every cylinder full stroke for every movement so you adjust it once and never again. When i put it on the car it will be only the cylinders and nothing else all the others i have put them just to help me write the program. At the video i work it at 6 bar and almost the half air flow at the car i can go at 10 bar maximum if i want so imagine the speed i can go double faster than the gearbox can effort. And the most important is that anytime i want i push "off" and i work the gearbox like it was before with the stick without any diferense something that with selespeed you cant doit. And as i think it my gearbox will last more time with this because the changes will be more acurate.And i have payed nothing to fiat thats good too and i fix it by my own so i am proud for this and you can say everything you want. I can hear any opinion good or bad but not from "people who knows everything but propably only in theory because practical i have never see something they have fix. Thanks the rest people for the suport

Good for you.
Our country was made a great one by people playing around with existing ideas and making them better. Did somebody tell James Dyson not to bother inventing has vacuum cleaner because Hoover got there first? Probably lots of people did, but he ignored them and Dyson is now one of our greatest companies.
I hope Panoramix goes on to achieve something special where he lives, and I am sorry that he has been given the impression that we are technical snobs.
 
Nice to see Andy making friends in his unique way. :cry:

panoramix3519- A nice project, but you've got to admit it's a bit rough around the edges... but then it is clearly a prototype, so you've got to expect it to not be a refined piece of production-ready engineering.

In all seriousness though, have you looked into other products already on the market? One that I've seen a lot of is the Ikeya Formula Shifter (granted, not available for Fiats) that converts the 'H' pattern to a simple push/pull sequential action via some clever engineering at the lever-end.

It would do away with the need for several bulky cylinders, sensors and linkages, replacing them with possibly just a single unit, similar to the "Ghost-shifter" modification.

i have seen the ykeya but the problem with this is that its designed for dogbox so when you make a gear change moves both of wires together but the one slower than the other and second i want to be more customable and with everything adjustable. And the biger problem for me i dont want to change something at my car so when i finished mine everytime i want i can work the stick like before this is very important for me. I never said that it is perfect and as construction is only for example but is customable to every thing i want speed power everything so until its finished it will be much better than this. The best is the happy i feel that i fix it like i want and it is fixed from me not from fiat to do what i want not what fiat wants i hope you understand because my english is not so good. I just want to share with you something i have done i dont say that fiat will buy it for the next model :):):)
 
i love messing but i couldnt do what hes done
im sure andy will realise that he should encourage people rather than denigrate them when they are willing to go to the trouble of showing what they are doing
 
working but not finished yet. I am testing every day and go a bit faster everytime. This is the slower speed that can go. As you can see it has safety for anything that could be wrong so it will not let me to do anything wrong and damage the gearbox even if i want and untill now 2 weeks working is absolutely acurate and stable.
sory i forgot the link

how long before he turns it off because it reminds him of the missing airbag?

of course some of us lived before flashing airbag messages so a bit of duct tape should easily rectify the solution or a 3.9 ohm 5 watt resistor:D

keep up the good work panoramica12345:)
 
How do you put it into neutral?

What are you going to do when you're doing 70 down the motorway and your plc bugs and won't change gear or tries to put it into first?

If your cylinders are pneumatic, how are you going to generate the air pressure?

he's got 3 buttons on the wheel
Up
Down
return to neutral

And if the system bugs - yea i'd be curious? Just flick the switchs and overide to complete manual?

And he's got an aircompressor in the boot generating air :)

yep its all in the video to watch:D
sometimes speed reading/watching is a bard fing
 
If the plc bugs you push the off button and everything is like it was before. I am working it one week now and never bugs for everything it can be go wrong i have write second safety program and push the clutch and go to neutral. If you see at the video all the positions has sensors so it checks every movement if its ok and how long time need to do it so if logo see something wrong or wrong time it will go to neutral. If you see better i conect all the cylinders with that way that when every valve is off the stick goes to neutral. Until now never bugs and if bugs as you understand it has to many safetys i can say more safetys than sellespeed that the only safety that has is a potentiometer. And as i wrote to the video is not finish yet, i am just testing. In this video is working at 5bar and at my compressor i have 12bar. And the flow regulators at every pneumatic cylinder is at 1/8 of the flow so you can understand how fast this thing can go but i want to test then go little faster then test again and then again little faster.
 
Today i measure it with an accelerometer and its making a full gear change with clutch in auto in 0.4sec from 2 to 3. And all this with the air pressure at 5.5bar from 12 that ia have in my boot and the air flow at 1/8. The thing i have done is to wright a secondary program that you can choose from the buttons at the steering. So if you want you can do normal changes at 0.7sec from 2 to 3 or you can change fuction and make gearchanges at 0.4sec. The differense is that to the second program i am combine cylinder moves so i am making round moves like the hand and not corner moves like you have seen at the video. Now i am working at the launch control for flat shift without the need to get the foot from throttle pedal.
 
Hello panoramix.

Reading this topic.. I had to register and give my reply also :)

First, nice work on this system. I don't think that this has been done pneumatically before you. So hats down for the idea and for actually doing it. Idea is just that.. an idea. To make it work and finish it actually, it's another story. So congrats.

Second, to AndyRKett - Please show us your never-before-seen projects and top innovations so we can comment them.

Third.. you guys talk about selespeed for alfa and it's 0.7s shift. Are you f**** serious? Every decent driver can shift under 0.2 by hand on any H gearbox.

I've been designing paddle shifting systems for 8 years and I've seen gearboxes shift in under 60ms, that 0.06s, so 10 times faster than your "selesspeed" gearbox.

Please know the facts before ****ting all over the forum with this attitude.

My appologizes to other nice people here, I know I can't judge this from one person.

There is one person on this forum who is renowned for being a know - all, totally un - diplomatic, and would rather shoot people down than encourage. Those of us who are used to him are used to him but to newcomers it can paint the forum in a very bad light. He once famously claimed that a terrible incident that had occurred and been given world-wide coverage was an internet hoax, just on the basis that he had somehow not seen it.Just ignore him is the best policy.
